Title: Improvements relating to flow measuring apparatus
IPC: G01F15/02
Filed: 1926-08-31
Abstract: 258,248. Siemens & Halske Akt.- Ges. Sept. 8, 1925, [Convention date]. Pressure gauges. - A differential pressure gauge indicating the rate of flow of steam or vapour operates a rod 1 to slide an iron core 2 between the pole-shoes 3, 4 of a yoke 5 which is excited by a coil 6 fed from the alternating current means 7. The current induced on a coil 8 and passing through an ammeter 9 and watthour meter 10 is thereby varied. The readings of the meters 9, 10 thus indicate the rate of flow and quantity of steam delivered. In the apparatus shown in Fig. 1, these readings are corrected for pressure or temperature by rotating an iron armature 12 by means of a pressure or temperature indicator 20 between pole-pieces 11 forming a shunt for the lines of force induced in the yokes. In the apparatus shown in Fig. 2, this correction is effected by passing the current induced in the coil 8 through the choke coil 13 having pivoted yoke-pieces 14, 15 attached respectively to a pressure indicator 18 and a temperature index.

Abstract: 271,303. James, R. W., (Brown Instrument Co.). Aug. 31, 1926. Integrating. - In a recording meter wherein a continuous record of the instantaneous value is produced on a recording surface, means are provided for obtaining a record of progressive increases in the integrated value of the quantity measured. As shown in Fig. 1, applied to a flow meter of the type described in Specification 266,616, a recording arm F produces a record on a disc K and an integrator control arm H determines the amount of rotation imparted to a disc U by a constantly rotating cam disc M<1> so as to control the actuation of a counting-mechanism I. The actuation is effected through worm gearing U<1>, W<1> and a power driven shaft X, Fig. 5, by an arm I<3> oscillated by a cam Y adapted to be coupled to the shaft X on each revolution of the shaft W through a pawl Y<1> and ratchet wheel X<1> secured to the shaft X. The arm I<3> is extended to engage a pawl carrying arm Z' actuating a ratchet wheel Z in a stepby-step manner. An arm f<3> co-operates with the wheel Z and operates a recording arm f to produce records K<6> representing increments in the integrated quantity. One of teeth Z<3> of the wheel Z is provided with a shoulder Z<4> so as to produce the records K<7>. thereby dividing the recording lines into groups. In a modification shown in Fig. 6, the counter actuating device U is geared to a ratchet wheel ZA co-operating with the recording arm f to produce a record K<8>. A lever I<8> bearing on the arm f<3> serves to actuate the counter I.

Title: Curing glycidyl polyethers with m-phenylene diamine
IPC: C08G59/50
Filed: 1954-07-27
Abstract: Glycidyl polyethers having a 1,2-epoxy equivalency greater 1 than are cured with meta-phenylene diamine.  The diamine may be used with other substances, e.g. as a eutectic mixture with ortho-phenylene diamine and/or p,p1-diaminodiphenyl methane, or with metaaminophenol. The diamine may also be used in admixture with carboxylic acids, e.g. 2-ethyl hexoic acid.  Curing occurs slowly at 20 DEG  C. but is usually performed at 50-280 DEG  C. Partial curing to a fusible, acetone-soluble stage may be completed in a later stage.  The polyethers are preferably melted or dissolved and diluted to lower their viscosity.  Solvents and diluents are listed and include mono-epoxy and other compounds which remain in the cured products. Curable compositions may include conventional ingredients such as pigments, fillers, dyes, plasticizers.  The products are useful for laminates or fibre-reinforced articles, especially those containing woven glass cloth.  Moulding powders may be pre-formed to pellets. Examples describe the curing of various glycidyl ethers of bis-(4-hydroxyphenyl)-2,2-propane and of the glycidyl ether of glycerol.  Comparative figures are given for similar curing agents showing that m-phenylene diaminecured resins retain their hardness well at elevated temperatures and have good resistance to acetone. The shelf life of curable compositions containing m-phenylene diamines is also good and cured products are not greatly discoloured. Examples relate to cast products, laminates and moulded products.

Abstract: 812,877. Radio direction finding. DECCA RECORD CO. Ltd. Oct. 7, 1957 [July 10, 1957], No. 21913/57. Class 40 (7). A radar apparatus of the type that uses an aerial which both scans in azimuth and node has a time-varied gain control adjusted in synchronism with the elevation of the aerial so that a reduced response to ground-clutter without loss of shortrange cover on high-flying targets is obtained. One possible form of gain/range characteristic is shown in Fig. 3 and it is seen that at low aerial elevations the gain is reduced from the maximum over a certain range, indicated by the full line, while at higher aerial elevations the range over which the gain is reduced is smaller, the gain characteristic at one such higher elevation being illustrated by the dotted line. The variation in gain with elevation and with range may be performed in steps or continuously and the maximum gain may be either at maximum elevation or below this point. In locations where the ground-clutter is unevenly distributed the gain may be further varied with the bearing of the aerial and in another embodiment the gain is reduced in accordance with the amplitude of the signals received during an immediately preceding period.

Title: Improved winding means for the controlling ropes of the conductor-trolleys of electrically propelled vehicles
IPC: B60L5/16
Filed: 1937-08-09
Abstract: 490,970. Spring drum apparatus. DELACHAUX, C. L. Aug. 9, 1937, No. 21949. Convention date, June 1. [Classes 78 (ii) and 104 (iii)] A spring-drum apparatus for taking up the slack in the rope that is used to position the trolly of an electrically-propelled vehicle or to restore it into contact with the conductor cable after it has escaped such conductor, and also for preventing sudden upward movement of the trolly arm following the escape of the trolly from the conductor comprises a drum 3 loose on a shaft 2 and having a light spring 5 anchored between the shaft and the drum sufficient to take up the slack in the rope 4 which is wound on the drum. A powerful spring 6 sufficient to neutralize the trolly-arm raising devices is anchored between a stationary casing 1 and the hub 7 of a plate 8 keyed to the shaft. This spring is maintained tensioned by the engagement, with one of a number of notches 15 inside the casing, of a pawl 13 pivoted on the plate 8 and biassed by a spring 14 into such engagement. Catches 17 are pivotally mounted on the end wall 9 of the drum 3 and are normally drawn inwardly by springs 18. Slow rotation of the drum under the action of the light spring 5 has no effect on the catches 17 but when the drum starts to rotate rapidly when the trolly slips off the conductor the catches fly outwardly by centrifugal action and the nose of one of them engages a notch 16 in the pawl 13 and releases the pawl from the notch 15 so that the drum 2 is now coupled to the powerful spring 6 which rotates the drum in the reverse direction to that in which it was being rotated under the action of the trolly-arm raising devices. The spring 6 is retensioned by a crank handle 19 which may be removably secured to the shaft or may be connected thereto through a one-way mechanism. To prevent injury to the light spring during the rewinding of the spring 6, the spring 5 is secured to the shaft 2 through a oneway arrangement also.
